From the foregoing description the op eration of 'my improved machine will be readily understood when taken in connection with the accompanying drawings and.

the following statement. The position of the parts shown in the drawings are their normal or operative position, and when itis desired to slicea piece of meat for example, the same is placed upon the table 64 and the gripping plate moved inwardly to force said meatagainst the gage plate40, after'which the backing plate 73 is moved forwardly into engagementwith the rear end portion of the meat, it being understood that the gage plate 40 has been adjusted to determine the desired thickness of the slice to be cut from said meat, after which the crank 21 is operated to rotate the rotary disk knife 17 in which operation the left hand of the operator grasps the gripping plate 67 and the vertical portion 65 of the table'fi t, and

the meat supported on said table between the gripping-plate and the gage plate/t0 is moved backwardly by hand, or

y sliding said table 64 backwardly over the base plate 62 of the frame, as will be readily understood, in which operation the baekingplate 73 operates-to prevent the sl pping of themeat of from the table 64 both in the forward as well as the backward movement of said table. Therotation of the rotary knife 17 in the saw-cut 26 in the sheet or strip 24 forms a scissor cut for the meat, or the like, between said knife and the plate 24, as will be readily'understood; and in this way or by means of this construction a perfcctly clean cut is obtained.
